The first pump empties half the pond in 3 hours, so in 1/6 that time (1/2 hour), it empties (1/6)·(1/2) = 1/12 of the pond.
The second pump empties the other 5/12 of the pond in that half hour, so has a pumping rate of (1/2 h)/(5/12 pond) = (6/5 h)/pond.
The second pump could do the entire job alone in 1 hour and 12 minutes.

Answer:
Step-by-step explanation:
We have been given two points on a line and . We are asked to write an equation passing through these points.
We will write our equation in slope-intercept form of equation , where,
m = Slope of line,
b = Initial value or the y-intercept.
Let us find slope of given line using slope formula.
Let point and point .
Now, we will substitute and coordinates of point in slope-intercept form of equation as:
Upon substituting and in slope-intercept form of equation, we will get our required equation as:
Therefore, our required equation would be .
